Low Temperature Preparation of ZnIn2S4 by Hydrothermal Method and its Visible Light Photocatalytic Property
Abstract:
In this paper, ZnIn2S4 crystals are synthesized in one step at 45°C~65°C by using hydrothermal method and the sample is identified via such technologies as scanning electron microscope, x ray diffraction and UV-visible spectrum. The results show that: hexagonal structured crystals can be prepared at the above-mentioned synthetic temperature; as to the sample obtained at 65°C, its average grain size is about 20~50um and it has a petal-like surface. Taking this ZnIn2S4 microsphere as a catalyst to catalyze the degradation of methyl orange under visible light, the degradation rate of the methyl orange after 2h illumination is above 97% and 100% after 2.5h. This indicates relatively high activity of degrading methyl orange.
